Fuel Pressure Regulator

Hello,

In the end, I bought a used Bosch regulator.
Well, it’s a world of difference compared to the Skandix one. It holds pressure well (still 1.9 bar after 15 minutes), and the pressure gauge needle is very steady.

Who manufactures the Skandix regulator? There are no markings on the part itself, and the box just says "Importer Skandix."

After opening a PayPal dispute, they agreed to take the part back. I am waiting for the refund.
